Hey ade,
I did as u suggest.
I checked out for 'linkdata' function, but it is not there in help. I also could not found any icon which link plot to workspace. If you talked about' show plot tools and dock fig', it doesnt work.
Also in real-time chart i want to show x-axis as time axis and want to plot temperature values on y-axis.

Nandish,
I do not have access to MATLAB right now, but check out this website.
http://www.mathworks.com/access/helpdesk/help/techdoc/ref/linkdata.html

Your version of MATLAB might also not include that function. I have 2008b, and 2010a, and the function is in both version. So if you are using a much older version, it might not be in that version.
